The basis of a contract. Consideration is a benefit or right for which the parties to a contract must bargain; the contract is founded on an exchange of one form of consideration for another. Consideration may be a promise to perform a certain act -- for example, a promise to fix a leaky roof -- or a promise not to do something, such as build a second story on a house that will block the neighbor's view. Whatever its particulars, consideration must be something of value to the people who are making the contract.

A seller's taking advantage of a buyer due to their unequal bargaining positions, perhaps because of the buyer's recent trauma, physical infirmity, ignorance, inability to read or inability to understand the language. The unfairness must be so severe that it is shocking to the average person. It usually includes the absence of any meaningful choice on the part of the buyer and contract terms so one-sided that they unreasonably favor the seller. A contract will be terminated if the buyer can prove unconscionability.

Property that carries a right to use a portion of a neighboring property. For example, property that benefits from a beach access trail across another property is the dominant tenement.

The substitution of a new contract for an old one. A novation may change one of the parties to the contract or the duties that must be performed by the original parties.

An extraordinary and unexpected natural event, such as a hurricane, tornado, earthquake or even the sudden death of a person. An act of God may be a defense against liability for injuries or damages. Under the law of contracts, an act of God often serves as a valid excuse if one of the parties to the contract is unable to fulfill his or her duties -- for instance, completing a construction project on time.

A person to whom a property right is transferred. For example, an assignee may take over a lease from a tenant who wants to permanently move out before the lease expires. The assignee takes control of the property and assumes all the legal rights and responsibilities of the tenant, including payment of rent. However, the original tenant remains legally responsible if the assignee fails to pay the rent.

A rental agreement or lease between a tenant and a new tenant (called a sublessee) who will either share the rental or take over from the first tenant. The sublessee pays rent directly to the tenant. The tenant is still completely responsible to the landlord for the rent and for any damage, including that caused by the sublessee. Most landlords prohibit subleases unless they have given prior written consent. Compare assignment.
